More changes to come

(Updated with info on Verizon tech) Apple has released a relatively minor update of iOS, 4.3.3. The upgrade does however fulfill an earlier promise by improving the security of location data. The size of the location cache file has been reduced, and the cache should no longer be included in iTunes backups. When Location Services are switched off, the cache is deleted entirely, Apple says.

The update is available through iTunes; download size is dependent on the device. Compatible hardware includes iPads, the iPhone 3GS, the GSM iPhone 4 and third- and fourth-generation iPod touches. Apple is not done addressing complaints with the security of iOS, as the next step is a planned "major" iOS update which will do on-device encryption of the location cache. When that might arrive is uncertain.

Update: For Verizon iPhones Apple has pushed out v4.2.8. Changes are identical to those of v4.3.3.

Cirrus creates Lightning-headphone dev kit

Apple supplier Cirrus Logic has introduced a MFi-compliant new development kit for companies interested in using Cirrus' chips to create Lightning-based headphones, which -- regardless of whether rumors about Apple dropping the analog headphone jack in its iPhone this fall -- can offer advantages to music-loving iOS device users. The kit mentions some of the advantages of an all-digital headset or headphone connector, including higher-bitrate support, a more customizable experience, and support for power and data transfer into headphone hardware. Several companies already make Lightning headphones, and Apple has supported the concept since June 2014. http://bit.ly/29giiZj

Apple employees testing wheelchair features

New features included in the forthcoming watchOS 3 are being tested by Apple retail store employees, including a new activity-tracking feature that has been designed with wheelchair users in mind. The move is slightly unusual in that, while retail employees have previously been used to test pre-release versions of OS X and iOS, this marks the first time they've been included in the otherwise developer-only watchOS betas. The company is said to have gone to great lengths to modify the activity tracker for wheelchair users, including changing the "time to stand" notification to "time to roll" and including two wheelchair-centric workout apps. http://bit.ly/2955JDa

Twitter stickers slowly roll out to users

Twitter has introduced "stickers," allowing users to add extra graphical elements to their photos before uploading them to the micro-blogging service. A library of hundreds of accessories, props, and emoji will be available to use as stickers, which can be resized, rotated, and placed anywhere on the photograph. Images with stickers will also become searchable with viewers able to select a sticker to see how others use the same graphic in their own posts. Twitter advises stickers will be rolling out to users over the next few weeks, and will work on both the mobile apps and through the browser. http://bit.ly/29bbwUE
